Surface plasmon polaritons (SPPs) have several unique properties, including their strong-field enhancing effect in near field. This means, among other things, that nonlinear phenomena may be studied at much lower laser intensities. The present paper describes in detail the theory of basic properties of SPPs, and our model of a laser-induced oscillating double-layer potential. The SPPs may decay into photons and hot electrons. The latter may be emitted by a multi-plasmon process. Experiments on both photon and electron emission from a gold film are briefly presented.
